To all 'whom t may concern: 'v

Bel it known that I,.JoHNIM. Consola, a citizen ofthe United States, and a resident-of the city of New York, boroughvof Brooklyn, in the county `of Kings and State of New York, have invented-new and. useful Improvementsin Furnaces, of which the followingl is a full, clear, and exact description. y

This invention'relates to-improvements 1n furnacesand more particularly to improved means for admitting heated air to thel ire box of the furnace, and while I shall hereinafter referto the device as a furnace it is,''of course, to be understood that I use this term in its broadestpossible sense to includeany stove or heater-with which my invention may beemployed. The improvement is,.'however, particularly adaptedfor use in connection with'the fuel door of a furnace and is illustrated and described as such. 4

An object ofthe inventionis to provide an'fattachment or adjunct to the door and the door frame whereby a plurality of air Vinlet ues are formed, communicating with the damper of the doorv 'and discharging over the top of the fuel in the fire box, and

to so constructl and arrange the parts that the'fair will be subjected to the vmaximum of heat from'wa Vrelatively large radiating metallic surface and will be distributed in a wide sheet or stream" over the top of the fuel so as to supply the necessary heated oxygen to aid combustion and prevent choking of the fire, wasting ,of the gas, and loss of heat.

A' further object is to provide improvements of the character stated which may be attached to a furnace door ofv a construction in general use or may be installed on doors and frames in the course of manufacture and which add but little to the cost of construction while at the same time resulting m a great economy in fuel consumption as well as beneficial results of combustion.

With these and other objects in view, the invention consists in certain novel features of construction and combinations andv arrangements of parts which will be more full hereinafter described and pointed out in t e claims.

In the accompanying drawings- Figure 1 is a view in front elevation,

partly broken away, illustrating my invena tion as' applied to the fuel door and to the door Vframeof a furnace; Y

' Figure 2 is a View in `vertical section on the line 2--2 of Figure 1 ;A

`li`igure 3 is a 'view in horizontal section on the line 3-3 of Figure 1.

l represents an ordinary furnacel door having hinged Vconnection as shown at 2 with the door frame 3. Thisy door frame a 3l is a lsecured to the furnace wall 4 in any approved manner, and I would have it understood that 'I have not attemptedto illustrate in detail the construction Vof any par!l ticular furnace as it is obvious that the vand is shorter than the door and spaced fromvf the bottom thereof 'for a purpose which will hereinafter appear. Webs orY ribs f7 are madev integral with the plate 4 or otherwise formed thereon, andthese webs extend upwardly to a point of communication with the inner face of the door, back of theldamper. This'fdamperfl is illustrated as ofthe ordinary rotary type, but, of course, mayy be of any other type with which doors are ordinarily equipped. The

central web is relatively straight and the other websV at both sides thereof are inclined, forming a series of air flues 9, having their entrances in communication with the damper 8 and their exits in `communication ywith similar flues 10 formed b a plate 11 secured to the bottomof the oor frame 3. The plate 1l has webs 11 corresponding in number to, and registering with, the webs 7 so that the flues 9 vand 10 `are continuous and the airA is directed through the same above the fuel 12 in the fire box 13.`

In attaching this improved plate 11 to the frame 3, where it is used on furnaces such as now in common use, I employ bolts,

' rivets or other securing devices 14, but it is, of course, to be understood that where V the improvement is applied to lfurnaces in the course-of construction the plate 11 andl the Webs 1l may be cast integrally with the door frame 3; in other Words, formed `as ,a fixedrpart thereof and not Aa separate at,- tachment.

By reason oi" the construction and ar rangement of parts such as abover described,

the air is divided or distributed from the wise waste products of combustion escaping from the Jfurnace.

Various Aslight changes and alterations might lbe made in the general form .of the parts described Without departing from 4my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty 4to make such Y slight changes and alterations as fairly -fall Within the spirit and sco-pe of the appended claims.

I claim:

1. 'llie cnmbination Wilia furnace doer having an air inlet therein, of zi-plate Secured tothe door., and Webs .on the Plate spacing the same from the inner face of the door constituting a wall around the let and 'torminga plural-ity of flues .coni-v municafting with the air inlet and directing 'die air downWardly to the bottom of .the door.
